No support for NFC tokens You don't do anything that OpenKeychain doesn't, and fail to do some of what it does. Back-porting features from OpenKeychain, you missed the most important one - it's ability to use keys on NFC-accessible hardware tokens such as Yubikey NEO. I think this omission is far more important than your ability to accept public keys from another phone via NFC. Uninstalling.
Near Perfect Keychain Management For Android What more can I say? This thing is nearly perfect. I was looking for a way to handle PGP on my phone and every recommendation pointed me this way. What I like is that it is flexible in the way that it handles PGP content, whether it be keys, encrypted files, clipboard content, etc.. I seen that it has good integration with K9 email client, but I've done just fine using it with gmail on my phone with no problem. Importing secret keys is pretty straightforward and easy. No serious issues with this app so far.
EXCELLENT APP! I never though I'd be able to send a sms encrypted with a 4096 bit RSA key but here we are and I can do exactly that or encrypt my emails. Thank you now nobody can read my texts or email. Oh nearly forgot great to see it creates 4096 bit RSA key by default most clients are 2048 by default. 5 stars for sure. Will keep an eye out for any other apps you may do.
K9 mail integration Love it! Being able to send PGP encrypted signed mails is a great feature for mobile. The only reason people say the keys "aren't secure" is a limitation of mobile hardware. Supposedly the entropy collection on mobile devices is inferior to that of traditional hardware. If you're that concerned, generate the keys on your desktop and import them like I did. Also, storing keys on your phone is considered a security risk. Small request though. SHA512 signature support?
Best PGP manager for Android I use PGP on a regular basis and this integrates well with k9mail. The last update makes the usage of the app pleasent. The interface is gorgeous! I haven't personally tested it since the last few updates, as I already have one, but last time I used it to generate a key it took almost 15 minutes for a 4096 bit key and from what I heard it was an insecure.
Works I need independent encryption for work & APG along with K9-mail makes that practical on mobile. I wouldn't object to a slick interface or addnl key management features but neither is really necessary. The functionality is there and that's what really matters: 5-stars
